Domain weightings

How much of the exam each domain covers. Spend your study time in proportion — the heavier the domain, the more questions you'll see.

Key terms

REST API

A REST API exposes resources over HTTP using verbs and JSON, and is the primary way Cisco platforms are automated programmatically. AUTOCOR covers consuming REST APIs to automate Cisco platforms.

JSON

JSON is the lightweight data-interchange format used in REST API requests and responses and in many config artifacts. AUTOCOR expects you to parse and construct JSON when scripting automation.

YANG

YANG is the data-modeling language that defines the structure of configuration and state data consumed by NETCONF, RESTCONF, and telemetry. AUTOCOR covers model-driven programmability with YANG.

NETCONF

NETCONF is an XML/RPC protocol for programmatically editing device configuration and state against YANG models. AUTOCOR covers NETCONF and RESTCONF for network automation.

RESTCONF

RESTCONF exposes YANG-modeled data as RESTful HTTP resources, a simpler alternative to NETCONF for many automation tasks. AUTOCOR covers RESTCONF among programmability interfaces.

Ansible

Ansible is an agentless automation tool that uses YAML playbooks to configure devices idempotently over SSH or APIs. AUTOCOR covers Ansible as an infrastructure-as-code tool for Cisco platforms.

Terraform

Terraform is an infrastructure-as-code tool that declares desired state in HCL and reconciles it through providers, including Cisco providers. AUTOCOR covers Terraform for declarative infrastructure provisioning.

CI/CD

CI/CD (continuous integration/continuous delivery) automates testing and deploying code and network configuration through pipelines. AUTOCOR covers CI/CD practices for network automation and NetDevOps.

Git

Git is the distributed version-control system used to track and collaborate on automation code and configuration as code. AUTOCOR expects Git workflows (branching, merging, pull requests) for infrastructure as code.

Webhook

A Webhook is an HTTP callback that pushes event notifications to a listener, enabling event-driven automation. AUTOCOR covers webhooks for integrating Cisco platforms into automated workflows.

Model-Driven Telemetry

Model-Driven Telemetry streams YANG-modeled operational data from devices for real-time monitoring, replacing SNMP polling. AUTOCOR covers telemetry for automated operations and assurance.

pyATS

pyATS (with the Genie library) is Cisco's Python test and validation framework for automated network testing and state comparison. AUTOCOR covers pyATS for operations and automated verification.

Python

Python is the primary scripting language for Cisco network automation, using SDKs and libraries to call device and controller APIs. AUTOCOR expects fluent Python for building automation.

AIOps

AIOps applies AI and machine learning to operational data for anomaly detection, insight, and automated remediation. AUTOCOR's AI in Automation domain covers using AI to enhance network operations.

Generative AI

Generative AI uses large language models to assist automation by generating code, configuration, and documentation from natural-language intent. AUTOCOR covers applying generative AI to network automation workflows.
